How Long Do Trailer Tires Last? – Because trailer tires carry heavy loads, such as boats, livestock and equipment, it’s important to ensure they are in proper condition. This includes proper inflation and ensuring that they have adequate tread and are not damaged by age.
From a tread depth perspective, trailer tires do not usually wear out. Tire manufacturers recommend tires be replaced every three or four years, regardless of how many miles have been driven on them or how much tread remains. This is because the structural integrity of trailer tires can be weakened by carrying heavy loads as well as improper storage. According to Discount Tire, in three years, roughly one-third of the tire’s strength is gone. The mileage expectation of a trailer tire is 5,000 to 12,000 miles.
